Solar AC for Home: Can Your Air Conditioner Run on Solar Power? (2026)
A solar AC setup lets your air conditioner run on rooftop solar power, reducing or eliminating the electricity cost of running AC during daylight hours.
TL;DR
Yes — your AC can run on solar power. A 1.5 ton inverter AC draws 1.2–1.5 kW per hour. A 3–5 kW rooftop solar system can power one to two 1.5 ton ACs during daylight hours while also running other home appliances.
How Much Power Does a 1.5 Ton AC Need?
A 1.5 ton inverter AC typically draws 1.2–1.5 kW per hour under normal Indian summer conditions (ambient temperature 32–38°C, room setpoint 24°C). A 2 ton inverter AC draws 1.6–2.0 kW per hour.
Key point: Inverter ACs modulate their compressor speed — once the room has cooled, consumption drops significantly below peak draw. Older non-inverter (fixed speed) ACs draw closer to 2 kW per hour at 1.5 ton capacity, making them more expensive to run and requiring a larger solar system for equivalent cooling hours.
For a detailed load analysis of what a 5 kW system can handle across all home appliances, see our guide on how many ACs can run on a 5 kW system.
What Solar System Size Do You Need to Run AC?
Recommended solar system sizes for common AC configurations in Indian homes:
3 kW solar system
1 × 1.5 ton inverter AC + basic home load (fans, lighting, fridge).
5 kW solar system
2 × 1.5 ton inverter ACs + basic home load.
7–8 kW solar system
3 × 1.5 ton inverter ACs + heavy home load.
For Bangalore homes with an average of 5–5.5 peak sun hours per day, a 5 kW system generates 22–27 units daily — comfortably covering two ACs running 5–6 hours per day plus all other home appliances.
